If you want to be coached by some of the best coaches in the world, then try an Airspeed camp. Their camps range from 3 (basic camps) to 6 (mega camps) days. You will learn a lot in either one and return to your home dz an entirely different skydiver. If you have the money I would say go for the mega camp. With that you will get about 2 hours of coached tunnel time. A basic camp is about 1 hour of tunnel time and you will still learn a lot, no doubt.
Airspeed camps run like clock work. There are 18 campers and 4-6 coaches. These 18 campers are divided into 3 groups of 6. There are usually 2 coaches to a group, each coach having his/her own sub-group of 3 campers who they are with the entire camp. Each day begins with stretching and from there each of the groups of 6 take turns flying 1/2 flights. So, within your 1/2 hour block you will fly 2or3 two minute flights with your coach. You will work through various skills, building as you go. After each flight in the tunnel you will have another 1/2hour to debrief with your coach, and the debriefs are thorough. After that you will prep for you next flight for a 1/2 hour while one of the other groups is flying and this rotation continues throughout the day.
Airspeed supplies lunch and food and drinks to "graze" on all day, so you don't need to worry about that. Each day ends with a very insightful lecture and then evening tunnel time. Not a second of the day is wasted and if you go, not a cent of your money will be wasted. There are people in these camps that range in jumps from just a few AFF jumps to thousands of jumps, and let me tell you that all of them learn and improve. It is remarkable and well worth it.
If you do decide to go to an Airspeed camp, or any camp for that matter, I would highly recommend working out a little before you go. The better shape you are in and the more you increase your flexibility, the more it will enhance your skydiving. That and the fact that you will be sore in places you never imagined before. (take some pain relievers) Also, if you really want to make it worth your while, budget for evening flight time. Even if it is 15 min. a night, it is completely worth it. The training during the day teaches you the skill, but with only 2 mins. per skill, you don't have a lot of time to really get it as good as you would like. Whereas the evening flight times allow you to work on anything you want. You could spend the entire time working on turns or bootie flying or whatever combination you would like, and it just really helps to drill the skills in. If you are unsure about evening time, just watch some of the other campers fly in the evening on the first night, and after that you will probably be the first to book time for the second night.
Airspeed camps are topnotch and the coaches are amazing. You will learn more in 3 or 6 days than you ever imagined you could. Good luck, and congrats to you for wanting to improve your skills and for doing so before you form poor habits that will be hard to break.
